IMPROVEMENT IN SPRING BED-BOTTMS.

Specification forming part of Letters Patent No. 146,453, dated January13, 1874; application filed July 10, 1873. i

To all whom it may concern:

Be it known that I, ALBERT W. HIGHT, of Princeton, in the county ofBureau and State of Illinois, have invented certain new and usefulImprovements in Spring Bed-Bottoms; and I do hereby declare thatthefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings and to the letters of referencemarked thereon, which form a part of this specification.

The nature of my invention consists in the construction and arrangementof a double-con- Vex spring bed-bottom, formed of a top and a bottomseries of slats, rmly united at the head and foot to cross-pieces, andsupported, at or near the center, by coiled-wire springs placed betweenthe two series of slats, all as will be hereinafter more fully setforth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in which-Figure 1 is a longitudinal section, and Fig. 2 a pian View, of mybed-bottom.

A A represent the top series of slats, and B B the bottom series. Theseslats are all firmly secured at the head and foot, or, in other words,at their ends, to cross-pieces C C by means of bolts, screws, or othersuitable means, the said cross-pieces separating the two series ofslats, as shown in Fig. 1. Between each slat and cross-piece is placed awasher, c, of rubber or other suitable material, to prevent all noiseand unnecessary friction. The slats of the two series are of the samenumber, and placed directly opposite each other. Between each top slat Aand its corresponding bottom slat B, at or near the center, are placedcoiled-wire springs D D, which thus support the slats, and the wholeforms a double-convex spring bedbottom. The springs D D are fastened inany suitable manner, and by any convenient means, to the slats, both ontop and bottom. Across the lower or bottom slats B B is fastened a bar,b, which forms a stiener, by which said slats are securely kept inposition and strengthene( The bedbottom thus constructed is cheap, yetstrong and durable, and has a very easy motion. A

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

In combination with the slats A and B and my own I affix my signature inpresence of two witnesses.
